'cosmic web' of galaxies, as seen in seven different fields on the sky

The 'cosmic web' of galaxies, as seen in seven different fields on the sky. Each dot is an entire galaxy. Time or redshift is displayed on the x-axis, such that more distant galaxies present in the early Universe are shown on the right side of the diagram. Galaxies are seen to cluster, in that some regions of space have a higher density of galaxies, while some regions have very few galaxies.
